Combine lemon juice, onion, garlic, cumin, black pepper, and steak in a large plastic zippered bag, and shake to coat steaks. Let marinate at room temperature for 30 minutes (or overnight, and take out of refrigerator 30 minutes before grilling).

Preheat outdoor grill (or use an indoor grill or stovetop grill pan). Remove the steaks from the marinade and sprinkle with salt. Sear steaks over high heat for 1 minute on each side. Then reduce heat to medium to medium-high, and grill about 4-6 minutes per side, depending on thickness of steak and desired degree of doneness.
